Lesions of the sheep reproductive system found in a slaughterhouse in the state of Bahia, Brazil / Lesões do sistema reprodutor em ovelhas de abatedouros frigoríficos no estado da Bahia

The present study aimed to evaluate and diagnose pathologies of the reproductive system of slaughtered sheep in slaughterhouses in the state of Bahia since there are few data on the subject as well as it is important to note the diagnosis of these diseases to apply appropriate control and prophylaxis measures. The research was carried out in slaughterhouses in the state of Bahia according to the "Serviço de Inspeção Federal" and "Serviço de Inspeção Estadual" for sheep slaughter. From July 2018 to February 2019, visits and monitoring of 1,072 slaughtered sheep were carried out. The animals came from 22 municipalities in the state of Bahia, aged from six to 18 months. During slaughter, the sheep reproductive systems were sectioned for evisceration and lesion collection. Additionally, epidemiological surveys related to origin, age, and race were obtained. For bacteriological examination, collections were performed with sterile scalpel slides and swabs in Stuart medium sterile tubes and refrigerated in a thermal box. For histopathological analysis, fragments were fixed in 10% formaldehyde and routinely processed for histology, stained with Hematoxylin and Eosin (HE). A study of the sheep's main pathological changes in slaughterhouses in the state of Bahia was carried out, in which 1.072 genital systems were evaluated, and 211 alterations were identified. The most affected reproductive organs were the ovaries (65.3%), followed by the uterus (29.4%) and uterine tubes (5.3%). In the ovaries, the most frequent lesion was a follicular cyst (34.1%); in the fallopian tubes, the cysts represented 3.3% of the lesions, and in the womb, endometritis was observed in 9% of the animals. Other pathologies identified in the ovaries were: luteinized cyst (2.3%); cystic granulosa cell tumor (0.5%); benign lesion (0.5%); agenesis unilateral (0.5%), in addition to other changes of little clinical significance, such as corpus luteum cysts (11.8%) and paraovarian cysts (15.6%). In the fallopian tubes, hydrosalpinx was observed (1%), as well as adenoma (0.5%), agenesis (0.5%), and cysts (3.3%). Uterine lesions included hydrometra (2.3%); Cystic Endometrial Hyperplasia (CEH), abscess, and pyometra (1.4% each); adenomyosis, womb sera petechiae, and total segmental aplasia (1% each); two pregnant uterus, in early pregnancy, presented pyometra (0.9%), however, no change was observed in the fetuses; and uterine polyp (0.5%). Ectopic pregnancy with fetal maceration (0.5%) was observed; vaginitis occurred in 0.5% of the animals, and endometrial melanosis in 8.5%. The high incidence of follicular cysts and endometritis are characterized as diseases that reduce the reproductive efficiency in herds, causing infertility and economic losses in production.(AU)

O objetivo do presente trabalho foi avaliar e diagnosticar alterações do sistema reprodutor de ovelhas abatidas em abatedouros frigoríficos no estado da Bahia. A pesquisa foi realizada em abatedouros frigoríficos do estado da Bahia com Serviços de Inspeção Federal e Estadual no abate de ovinos. No período de julho de 2018 a fevereiro de 2019 foram realizadas visitas e acompanhamento do abate de 1.072 ovelhas. Os animais eram provenientes de 22 municípios do estado da Bahia, com idade entre 6 a 18 meses. Durante o abate, na evisceração foram seccionados os sistemas reprodutores das ovelhas para avaliação e coleta das lesões. Adicionalmente foram obtidos inquéritos epidemiológicos relacionados à procedência, idade e raça. Para o exame bacteriológico, as coletas foram realizadas com lâminas de bisturi estéreis e swabs em tubos estéreis com meio Stuart e refrigeradas em caixa térmica. Para análise histopatológica, os fragmentos foram fixados em formol a 10% e processados de forma rotineira para histologia e corados pela hematoxilina e eosina (HE). Entre 1.072 sistemas genitais avaliados, identificou-se 211 alterações. Os órgãos do sistema reprodutor mais acometidos foram os ovários (65,3%), útero (29,4%) e tubas uterinas (5,3%). Nos ovários, a lesão mais frequente foi o cisto folicular (34,1%); no útero a endometrite (9%) e nas tubas uterinas, os cistos representaram (3,3%). Outras lesões identificadas nos ovários foram: cisto luteinizado (2,3%); tumor de células da granulosa (0,5%); adenoma (0,5%); agenesia unilateral (0,5%), além de outras alterações de pouco significado clínico, como cistos paraovarianos (15,6%) e corpo lúteo cístico (11,8%). Nas tubas uterinas observou-se, além dos cistos tubo-ovarianos (3,3%), hidrossalpinge (1%), adenoma (0,5%) e agenesia (0,5%). As lesões uterinas foram endometrite (9%), hidrometra (2,3%); hiperplasia endometrial cística, abscesso e piometra (1,4% cada); adenomiose, petéquias na serosa do útero e aplasia segmentar (1% cada); dois úteros gravídicos, em início de gestação, apresentaram piometra (0,9%), porém os fetos não apresentaram alterações; e pólipo uterino (0,5%). Observou-se uma gestação ectópica com maceração fetal (0,5%); a vaginite ocorreu em 0,5%, e melanose endometrial em 8,5%. Destaca-se a elevada incidência de cistos foliculares e endometrite que são doenças que reduzem a eficiência reprodutiva dos rebanhos, provocando infertilidade e perdas econômicas na produção.(AU)

The impact of HSF on endometrium

Summary Objective: We conducted the research in order to explore the impact of hydrosalpinx fluid (HSF) on endometrium. Method: HSF group: 261 patients with HSF scheduled to undergo laparoscopic surgery 3 to 7 days after menstruation in our center. Hysteroscopy would also be performed in order to observe the endometrial morphology during the surgery. Sixty (60) patients would be randomly selected for endometrial biopsy in order to detect the inflammatory cytokines TNF-a and IL-2 mRNA. Non-HSF group: 210 patients with no evidence of HSF due to chronic salpingitis or pelvic adhesion. IVF-ET treatment was performed after eliminating the factor of male infertility and hysteroscopy was conducted before the treatment. Fifty (50) patients underwent endometrial biopsy in order to detect TNF-a and IL-2 mRNA. Results: Hysteroscopy was performed in 261 patients with HSF and 210 patients without HSF. The incidence rate of endometritis manifestation among these two groups of patients was 37.2% (97/261) and 20.5% (43/210), respectively. The incidence rate of endometritis in the patients with HSF is significantly higher than in the patients without HSF (p<0.05). Sixty (60) patients from the HSF group and 50 patients from the non-HSF group were regrouped according to inflammatory and normal manifestation after the endometrial biopsy. There were 49 patients in the inflammatory manifestation group and 61 patients in the normal manifestation group. RT-PCR technology was adopted to detect the expression of inflammatory cytokines TNF-a and IL-2 mRNA in endometrial tissue. The level of TNF-a mRNA expression in endometrial tissues with inflammatory manifestation was higher than in normal endometrium (76.75±11.95 vs. 23.45±9.75, p<0.01). There are significant differences between them. The level of IL-2 mRNA expression in endometrial tissues with inflammatory manifestation was higher than that found in normal endometrium (80.56±13.35 vs. 35.12±8.35, p<0.01). There are significant differences between them. Conclusion: Chronic endometritis is related to HSF and may therefore affect endometrial receptivity.

Endometritis puerperal en nuestro medio / Postpartum endometritis incidence and risk factors

la infección genital postparto causa importante morbimortalidad. Se realizó un estudio de cohortes prospectivo observacional, que incluyó pacientes con parto vaginal o abdominal desde 19/04/2010 hasta 19/07/2010, para determinar la incidencia de endometritis y delimitar la población en riesgo. Se definió endometritis con al menos 2 de los siguientes: temperatura >38ºC, dolor uterino, dolor abdominal, loquios fétidos o ecografía patológica, sin otra causa de infección. Se registraron 1.472 partos. La inicidencia global de endometritis fue 2,5% (IC95%: 1,7-3,3); en partos vaginales 1,4% (IC95%: 0,7 - 2,1) y abdominales 4,8% (IC95%: 2,9-6,8). la diferencia fue estadísticamente significativa (p<0,001). En el análisis multivariado los factores de riesgo independientemente asociados fueron edad menor a 20 años y parto abdominal. Se descartó colinealidad entre ambas variables. Parto abdominal fue el único factor modificable. En este sentido deberían dirigirse las medidas de prevención y vigilancia.

Postpartum infection is cause of morbidity and mortality. To determine the incidence of postpartum endometritis and define the population at risk we performed a prospective observational study that included all the patients admitted for delivery to the Maternity service between 19/04/2010 and 19/07/2010. Endometritis was defined by at least two of the sequent: temperature >38ºC, uterine and lower abdominal pain, abnormal vaginal or cervical discharge or transvaginal ultrasound pathological findings. We registered 1,472 deliveries. Global incidence of postpartum endometritis was 2.5 % (95% Cl: 1.7-3.3); for spontaneous labor it was 1.4% (95% Cl:-2.1) and for cesarean deliveries 4.8% (95 %CL: 2.9-6.8) and this difference was statistically significant (p<0.001). Independent risk factors were age of 20 years or less and cesrean delivery. There was no colineality between both variables. Cesarean delivery was found the only modifiable risk factor for endometritis.

Incidência de endometrite citológica e desempenho reprodutivo em vacas de corte Nelore / Incidence of cytological endometritis and its effects on reproductive performance in Nelore beef cows

Avaliaram-se a incidência de endometrite citológica dos 29 aos 90 dias pós-parto e seus efeitos sobre o desempenho reprodutivo de vacas de corte Nelore submetidas a uma estação de monta (EM) de 90 dias. Foram utilizadas 49 matrizes Nelores, sem histórico de retenção de placenta, sem a presença de uma infecção uterina clínica, e com escore de condição corporal acima de 2,5. Realizou-se exame ultrassonográfico para avaliar a parede uterina e a atividade ovariana. O diagnóstico de endometrite citológica foi feito pela técnica de lavagem uterina, considerando-se caso de endometrite ≥5% de neutrófilos em cada lâmina. A incidência de endometrite citológica do rebanho foi de 22%, não diferindo entre as categorias analisadas (primíparas versus multíparas) (P>0,05), a taxa de concepção à primeira inseminação também foi semelhante entre primíparas versus multíparas (P>0,05), porém a taxa de gestação ao final da EM foi maior nas vacas multíparas (83,8%) quando comparadas às primíparas (50,0%) (P<0,05). A presença ou ausência da endometrite citológica não influenciou a taxa de concepção (P>0,05), tampouco a taxa de gestação ao final da EM (P>0,05). Conclui-se que o uso da citologia endometrial não se justifica como ferramenta de diagnóstico em vacas de corte Nelore.

Were evaluated the incidence of cytological endometritis from 29 to 90 days postpartum and its effect on the reproductive performance of Nelore beef cows submitted to a breeding season (BS) for 90 days. A total of 49 cows, with no history of retained placenta, without the presence of a clinic uterine infection, and with a body condition score above 2.5 were used. Ultrasound examination was performed to evaluate the uterine wall and ovarian activity. The cytological diagnosis of endometritis was done by uterine lavage, and endometritis was considering cases of ≥5% neutrophils in each blade. The incidence of cytological endometritis in the herd was 22%, and did not differ between the categories analyzed (primiparous versus multiparous) (P>0.05), and the conception rate for first insemination was also similar between primiparous versus multiparous (P>0.05). However, the pregnancy rate at the end of BS was higher in multiparous cows (83.8%) when compared to primiparous (50.0%) cows (P<0.05). The presence or absence of cytological endometritis did not influence the conception rate (P>0.05) nor pregnancy rate at the end of the BS (P>0.05). Therefore, it can be concluded that the use of endometrial cytological cannot be justified as a diagnostic tool in Nelore beef cows.

Expressão de MMP-2 e MMP-9 no endométrio de éguas saudáveis e portadoras de endometrite crônica / Expression of MMP-2 and MMP-9 in helth endometrium and in chronic endometritis of mares

Avaliaram-se, por método imunoistoquímico, a expressão e distribuição das metaloproteinases (MMP) 2 e 9 em amostras de endométrio hígido e de éguas portadoras de endometrite crônica. Foram utilizadas 60 biópsias endometriais. A MMP-2 foi observada na parede vascular, nas células estromais e no epitélio glandular, e a imunorreatividade mais intensa foi obtida nas células do epitélio glandular nas endometrites da categoria III e na parede vascular nos endométrios da categoria I. A marcação imunoistoquímica para MMP-9 mostrou-se difusa pelo endométrio e foi observada no epitélio luminal e glandular, na região da parede vascular, nas células estromais, endoteliais e do infiltrado inflamatório. Houve diminuição da marcação imunoistoquímica na região da parede vascular conforme aumentou o grau das lesões endometriais concomitante à diminuição da intensidade da reação. Não houve relação na expressão imunoistoquímica das metaloproteinases estudadas com o tipo de endometrite.

The expression and distribution of matrix metalloproteinases (MMP) 2 and 9 were evaluated in helth endometrium and in chronic endometrites of mares by means of immunohistochemistry method. Sixty endometrial biopsies were utilized. Expression of MMP-2 was observed in vascular wall, stromal cells, and glandular epithelium. More intense immune reaction was seen in glandular epithelial cells in category III endometritis and in vascular wall in category I endometrium. MMP-9 immune reaction was diffuse and was seen in luminal and glandular epithelium; vascular wall region; and stromal, endotelial, and inflammatory cells. There was a decreased of the immunohistochemical marking in vascular wall region as increased the degree of endometrial injury, as well as reducing the intensity of reaction in this compartment. There was no relation in immunohistochemistry expression of metalloproteinases with the type of endometritis.

Endocardite infecciosa valvular em uma cadela com endometrite: relato de Caso / Infectious endocarditis valvular in a dog with endometritis: case report

Objetiva-se relatar um caso de endocardite da válvula mitral em cadela da raça boxer, com seis anos de idade, que foi encaminhada ao HV da UFRPE. Durante o exame clínico o animal veio a óbito. Na necropsia notou-se no fígado um abscesso de três centímetros de diâmetro e no útero havia grande quantidade de material muco-purulento. No ventrículo esquerdo do coração percebiam-se várias formações de aspecto vegetativo aderidas à válvula mitral. À histopatologia evidenciou-se hiperplasia endometrial cística e endometrite purulenta. Nos fragmentos do coração constatou-se que as massas aderidas às válvulas eram constituídas por tecido conjuntivo frouxo, leucócitos, fibrina, debris celulares e sangue. Cultura da secreção uterina, do abscesso hepático e dos trombos valvulares revelou a presença de Staphylococcus sp. Os achados anatomo-histopatológicos e microbiológicos permitem concluir tratar-se de endocardite bacteriana valvular mitral vegetativa consequente a endometrite crônica.

The goal of this paper is present a case of mitral valve endocarditis in a 6-year-old female dog due chronic endometritis. The animal was guided to the Veterinary Hospital at Universidade Federal Rural de Pernambuco, Brazil, but the animal died during the physical examination. At the necropsy, a liver abscess, 3,0 cm in diameter, uterine with purulent content and some also vegetative formations adhered to the mitral valve were visually recognized in the left ventricle of the heart. Histopathologically, cystic endometrial hyperplasia (CEH), and purulent endometritis were observed. In the valves a mass adhered was present, which one was constituted by slack conjunctive tissue, leukocyte, fibrin, cellular scraps and blood. Uterine secretion, hepatic abscess content and the valvular clots culture revealed the presence of Staphylococcus sp. In conclusion, this case revealed the importance of the anatomohistopathological and microbiological diagnosis for the vegetative mitral valve endocarditis in dogs with endometritis.

Metaplasia óssea do endométrio: relato de caso / Endometrium osseous metaplasia: a case

Os autores relatam o caso de uma paciente que apresentou aborto seguido de infeccão, resultando em esterilidade secundária. Após curetagem uterina terapêutica, o laudo do exame anatomopatológico foi de endometrite crônica com fibrose, calcificacão e metaplasia óssea. Na evolucão, a paciente apresentou sinéquia de corpo e colo uterino. Apesar de rara, a metaplasia óssea endometrial deve ser considerada no diagnóstico de infertilidade. O presente relato salienta a importância do diagnóstico histopatológico e do conhecimento da etiopatogenia dessa entidade, sua associacão com a endometrite crônica e história de abortamento.

Pathological prediction of post-cesarean endomyometritis

A prospective blinded study was carried out on 80 patients undergoing cesarean delivery and receiving antibiotic prophylaxis. Amniotic fluid samples and decidual-myometrial biopsies were obtained at the time of the operation and examined to identify those incipiently infected patients. 15 patients developed post-cesarean endomyometritis and positive gram stain was detected only in eight of them. Significant histologic differences in decidual inflammation and myometrial polymorphonuclear cell invasion were detected in the group that developed post-cesarean endomyometritis compared with the group without endomyometritis. The patients who subsequently developed post-cesarean endomyometritis demonstrated greater numbers of bacteria in the myometrial biopsy compared with the group without endomyometritis as shown by acridine organ stain. These data showed that the technique of histologic detection of incipient infection and the detection of bacteria within the myometrial tissue provide accurate methods for the identification of the group at risk of development of post-cesarean endometritis

Significance of leukocytic infiltration in endometrial pathology

A retrospective histopathological study of 100 cases of endometritis collected from 1989 to 1992 examined at the department of pathology, college of Medicine and Sadam Medical. The clinical presentation of endometritis was irregular vaginal bleeding, menorrhagia, infertility, post menopausal bleeding and pelvic pain. Chronic endometritis mostly seen in patients of the age group ranging between 30-39 years. 92 cases [88.84%] of non specific endometritis, 4 cases [3.84%] of tuberculous endometritis and bilharziasis. Mixed infections are seen in 4 cases [3.84%]. Our study is to find the relation-ship between chronic endometritis and post abortion, post delivery, post hydatidiform mole pregnancy, menopause and with the use of intrauterine contraceptive device
